Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“While I was driving this vehicle, it had shut off while I was driving and I lost all power. It started back up like normal. This has happened twice and I'm afraid this could happen while I'm on the highway with my family. I see there was a recall involving this but not for my vehicle. This has happened to me just recently.”

“I was driving my 2003 Infiniti M45 on or around june 30, 2011 at 65mph on highway 290 near the wolf rd exit in chicago. All of a sudden while I was in the left lane, my car started jerking heavily and my power steering went off making the car really hard to steer. I looked at the dash and saw no warning msgs come on.... I carefully veered my car through heavy traffic towards the right lane and shoulder and I barely missed a truck coming in the far right lane! As I got to the shoulder and caught my bearings and was about to call an emergency tow truck a cop came and asked what happened. …”
